Abstract Multiattribute utility theory is commonly used to define and represent the decision-maker’s preferences under conditions of uncertainty and risk. A major issue in implementing this approach deals with the identification and generation of appropriate utility functions, especially in an often nonlinear and complex engineering design environment. Typically, the decision-maker’s preferences are provided through lottery questions rather than based on deductive reasoning to reflect the nonlinear tradeoffs among the attributes. The use of such an intuitive procedure can lead to inconsistent and inexact preference information that may result in inaccuracy and rank reversal problems. Alternatively, this paper presents an Interactive Preference-Modeling (IPM) method towards a consistent preference representation in engineering design. Focusing on the preference orientation by implicitly articulating the designer’s priorities, this method provides a methodical framework to check and eliminate inconsistency in preference information, and to accurately express preferences through rational pairwise comparisons. The development of IPM method and its utilization in the determination of the system utility function from a consistent set of local utility functions are presented in the context of a beam design problem and the results are discussed.

Abstrak:Penelitian ini bertujuan untuk mengetahui gambaran keefektifan sekolah dilihat dari delapan standar nasional pendidikan. mengetahui tingkat ketecapaian keefektifan sekolahdilihat dari delapan standar nasional pendidikan dan mengetahui dari kedelapan standartnasional pendidikan butir mana disetiap standart yang masih perlu mendapatkan perhatiansecara serius. Metode penelitian yang digunakan adalahmetode survai yakni upayamengumpulkan informasi dari responden yang merupakan contoh dengan menggunakankuesioner yang terstruktur. Populasi dari penelitian ini adalah jumlah satuan pendidikanSekolah Mengengah Pertama (SMP) sebanyak 349 sekolah yang bersatatus sekolah negeriyang menyebar di wilayah eks karesidenan Surakarta. Sampel diambil sebanyak 172 sekolahdengan pendekatan area probability sampling. Instrumen yang digunakan dalam penelitian inimerupakan kuesioner tertutup dengan skala likert. Setelah data terkumpul kemudian dianalisisdengan pendekatan kuantitatif secara deskriptif. Hasil penelitian menunjukkan bahwa dilihatdari standar isi; standar proses; standar kompetensi kelulusan; standar pendidikan dan tenagakependididkan; standar sarana dan prasarana ; standar pengelolaan; standar pembiayaan; danstandar penilaian sudah cukup baik. Ketercapaian delapan standar nasional pendidikan seluruhsekolah sampel sudah mencapai tingkat yang cukup tinggi yakni di atas 90%, kendati masihada beberapa dari sub butir standart yang masih perlu lebih diperbaiki Abstract:The aim of this research is to discover the school effectiveness seen from eightcomponents of standards of national education. From these eight components, we will find outwhich components still need to be regenerated. This research is using survey method bystructured questionnaire to gather information from respondents. The population is 349Government Junior High Schools in a region of ex Surakarta Residence. Total of samples frompopulation is 172 schools, using area probability sampling approach. To collect the data, weused closed questionnaire with Likert scale as the instrument. After all data collected, then weanalyze it descriptively with quantitative approach. The result shown that all the componentsof standards of national education, including content standards; process standards;competence of graduates standards; educational standards and human resource standards;facilities standards; management standards; funding standards; and assesment standards arefairly good. The achievement of eight standards of national education from all sample schoolsalready achieved high level, i.e. above than 90%. But still there are several sub componentsneeds to be regenerated.

The analysis of the concept, properties and features of heterogeneous redundancy in modern complex ergatic systems, including those included in the situation centers (SC). On the basis of the qualimetric paradigm, the generalized analytical model of quality and optimization of quality by private, group, summary and aggregated quality indicators is justified. Practical ways of realization of the model and methods of optimization of the objects which are a part of SC and them as a whole at the expense of reduction of structural, functional and other types of redundancy under the obligatory condition of non-reduction of the required value of quality are given. On the example of the generalized sampling theorem when choosing the optimal value of the sampling frequency of the real bandpass signal, the criticality and significant influence on the redundancy of data in their further processing in the SC is shown.
